IMPROVEMENT IN GANG-PLOWS.

Specification forming part of Letters Patent No. 58,386, dated October2, 1866.

To all whom it may concern:

Be it known that I, H. N. DALTON, of Pacheco, in the county of ContraCosta and State `of California, have invented a new and ImprovedGang-Plow, and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable those skilled in theart to make and use the same, reference being had to the aecompan yingdrawings, forming part of this specification, in which- Figure 1 is aplan or top view of my invention 5 Fig. 2, a side sectional view of thesame, taken in the line m w, Fig. l.

Similar letters of reference indicate corresponding parts.

Thisinvention relates to a new and improved gangplow, and consists of anovel construction and arrangement of parts, as hereinafter fully shownand described, whereby the plows may be readily raised and lowered atthe will of the driver,and also, when at work, kept in a proper positionin the earth.

A represents a rectangular frame, which is mounted on two wheels, B B,and has adraftpole, G, attached. The wheels B B are placed loosely ontheir axle D, and the latter is fitted loosely in the frame A, so thatit may turn therein.

The axle D has two arms, E E, projecting from it parallel with eachother, and through the outer ends of these arms E E a rod or shaft,a,passes, on which the front end of a rectangular frame, F, is littedloosely and allowed to swing or work freely. This frame F has two plows,G G, attached to it, one a little in advance of the other and out ofline with each other, or so as to work in different planes, so that thefurrow turned by the rear plow will lap properly over the furrow turnedby the foremost one.

H is a beam, the rear end of which is connected by two links, b b, withthe rear part of the frame F, and connected about at its center by twolinks, o c, with the rod or shaft a. The front end of this beam H has amortise made vertically through it, through which a vertical bar, I,attached to the front end of the frame A, passes, the beam being allowedto work or are performing their work the rearof frame F is preventedfromrising by means of a pin, e, passing through the bar I below thefront part of the beam H, the beam resting on said pm.

In order to elevate the plows the driver shoves forward the lever J, andthe front end of beam H first rises, the point-s of the plows beingmoved upward until the front end of the beam H strikes the pin d, whenthe rear part of the frame F rises, and the rear parts of the plows areelevated. This movement ofthe plows is effected by the arrangement ofthe frame F, arms E E on axle D, and the beam H, connected with theframes A F, as shown and described. This peculiar movement of the plowsis an important one, as it admits of the plows being raised out of theground with great facility, the result being effected by a very littleexertion on the part of the driver` and Without augmenting in a verymaterial degree the draft of the machine. y

Having thus described my invention, I claim as new and desire to secureby Letters Patent- '1. The plow-frame F, parallel arms E, beam H, linksb c, vertical bar I, and pins d e, combined and operating substantiallyas described, for the purpose specified.

2. The lever J, arms E E, beam H, and frame F, combined and operatingsubstantially as described, for the purpose specified..
